Topic : Chaotic Based Image Cryptography Using Wavelet
Transform

Authors:Dr. P Shanthi ||

Abstract:The main objective of the paper is to enhance the security of the images using chaotic map with wavelet transform.
Chaos-based image encryption method is one of the most efficient methods which is used to hide visual information during
transmission. This paper presents a new image encryption method based on Arnold cat map with Wavelet Transform, in which,
chaotic maps will change the pixels of the plain-image to encrypt that. Finally, the encrypted image will be decrypted to remake the
plain-image. To evaluate the efficiency of this method, it has been implemented with MATLAB and also has been measured by
doing some tests as analysis of Peak signal-to-noise ratio and adding salt & pepper noise. Simulation results show that the
proposed image encryption method has high accuracy while it is resistant to salt & pepper noise.
